Re: Boring/Facing head questions

I didn't try to address the wander of the head, just the constant feed, or depth of cut. I have NEVER (sadly) used a facing type head, although I have seen them, so I hesitated to address that issue. What I did try to address is the fact that the depth of cut determines the degree of deflection of a...

Re: Boring/Facing head questions

You don't understand what he means by depth of cut. Depth of cut is the amount of material removed per pass, and is NOT related to the depth of a given bore. By feeding the head while it's running, you may not be able to control the amount you can take, so it may not be a good idea. When trying to h...

Re: This is my workbench now, what can I do to improve it?

As Bill says, never overload your keyless chuck (s) with end mills or S&D drill bits. There's nothing more heartbreaking than watching a really expensive keyless chuck getting "unlocked" with a pipe wrench. It can be worse than that. Years ago I was gifted an almost new 1/8"-5/8" Albrecht that had ...

I'd sleeve it back to 1/2", and then make bushings with 1/2" O.D to accept 3/8", and 1/4" boring bars.
Yep! The best possible idea in my opinion.

Re: Boring Head Questions

but even if you have to move the bar to the other hole, you would still take a test cut and check the size before before the finish pass, Of course you would. You missed my point entirely. I didn't imply that having the holes the same size allows the bar to be moved from one hole to the other witho...

Re: Boring Head Questions

As far as making both holes some standard size, I was thinking about JB-Welding a plug in the 9/16" hole and then drilling it out to 1/2". Any thoughts on why that would or wouldn't work? Not necessary. A thin walled sleeve can be machined and used in lieu of that idea. It need not be split nor eve...

Re: Nice Shaper

There was a similar 36" shaper at Sperry, in the tool room. It sat unused almost 100% of the time. I think it was a Cincinnati. It, too, was hydraulic. A nice machine, but we had some K&T's that could outwork it easily. A lot of dead time on shapers and planers, time that is spent cutting on mills. ...

Re: Nice Shaper

This is on face book and this is really a nice shaper. Hmmm. Have you seen the machine, Richard? Interesting, but I suspect it looks one hell of a lot better than it is. Unpainted bits look like they're not in very good condition, and, frankly, paint does nothing in the way of improving a machine i...

Re: Tubes...leaking

Your posts are very vague and some might consider it "vaguebooking", to borrow a term from the #1 social media website. If you are just venting, then say so.. But if you are asking for help, you need to provide ALL of the information needed for those who want to help you, and then some. I've modera...

Re: Materials Question

(my hammers are 1" dia'). They make a 1" hammer with the replaceable tips, too, with a soft red rubber tip being available. I have one in my shop, with a green tip on one end and the red tip on the other. The green tip is somewhat harder, but neither of them damage steel components. I'd rather not ...
